browser_cookie3 only able to take cookies from Firefox and no other browser

Using the exact same code, all I changed was the firefox to chrome on the second line, and the code kept giving me:

TypeError: 'NoneType' object is not subscriptable

My code:

try:    cookies = browser_cookie3.firefox(domain_name='domain')    for cookie in cookies:        if cookie.name == 'cookie':            data.append(cookie.value)            return dataexcept:    pass

I tried browser_cookie3.load() -- similar results

I searched up fixes for my error -- nothing worked

I searched up the documentation -- I followed everything properly and no change.

Does anyone have a solution?
